PLATFORM-SCALE.

Specification of Letters Patent l\To. 26,512, dated December 20,1859.

To all whom 'it may concern:

Be it known that I, AMos B. MOREY, of the city and county of St. Louis and State of Missouri, have invented a new and useful Improvement in Platform-Scale Levers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making part of this specification, in which- Figure 1 is a perspective view. 2 a top view and Fig. 3 a side elevation.

My invention consists of a new way of constructing and bracing the lever of a platform scale, and will be understood from the following description.

A represents the principal bar constituting the lever, which consists of a fiat bar of iron of the form Shown and which is strengthened, and supported in the vertical and lateral direction by the application of the two braces B B, which are applied in a peculiar manner, to wit, with one end of each of the said braces applied to the side of. the main leverand in contact with it, and with the other end of each of the said braces, applied, and secured to the head or fixed upon'the end of the main lever in the manner shown so as to spread the inside end of the braces, and to increase their efficiency in the lateral direction, and to in crease the efficiency of these braces in this direction still moreand at the same time to cause them to brace the beam vertically Fig.

the triangular braces 0 0 and d are applied as to spread the braces as shown, and thus truss the lever in the center in both direclever from bending sidewise ordown in the 1 to the main lever, A andlthe braces, B B, so .1 1

center. Now to prevent the beam from bending down at the back end the braceve is applied to the head and the lever, asshown, l

and trussed with. the truss f, which thus. completes the construction. Now the object of this invention is to make a stronger and stiffer lever than has hitherto been made, with half the material,

and weight, than has hitherto been used in making platform scales--and I claim: that this object is accomplished in the above described method ,of making and. bracing the lever.

I am aware that truss braces have been.

applied to beams,'in bridges and roofs, and. t0 the connecting rods of steam engines in different ways andfor .difierentpurposes...

I do not therefore claim the application of truss braces to a lever or beam;broadly,yj so,

but

I claim-- The specific arrangement of the braces F B B, 0 0, d, e and f, with thelever A and I the head H as shownand described. y a A. B. MOREY. f Witnesses: i
